JOHN CONTI, OF PHZILADILPHIA., PENNSYLYAN PACKAGE-FILLING MACHINE.

Application led November 17, 1926. Serial No. 148,790.

My invention relates to packaging machinery and more particularly to a machine for filling paper lined cartons with crackers, biscuits or small cakes.

Under 'the usual method of procedure, crackerscome from Athe oven in large sheets and are broken apart and stacked by hand.

Small cakes are not usually baked in sheets but com'e from the Ovens in large batches 0f individual cakes, after which they go to a stacking machine whichpiles them in stacks ready for the packers to place them by hand in cartons; the cartons having previously been made, formed and lined withwaxed 41 5 paper by machinery.

Another object of my invention 1s to provide a machine in which empty cartons are automatically brought into position to be filled and the filled cartons removed.

These objects, and other advantageous e ends which will be described hereinafter, I

80 attain in the following manner, reference had to the accompanying drawings in Figure 1 is a side elevation of an embodi` ment of my invention, and Y vFigure 2a rearview'of the machineshown lin Figure 1. t

Figure 14a perspective view of thel rear paper guide. c

Referring more particularly to the drawings,l the frame of the machine consists of a 7@ pair of rear posts 15 and 15a and a pair of front posts 16 mounted on asuitable base 17a a pair of longitudinal top pieces 18, a pair of transverse top pieces 19, and a center top piece 20. It is understood,lofcourse, '75 that the base 17 would ordinarily be the Hoor of the bakery in which the machine `is. in;

A trough-shaped conveyor section 21I is mounted on base 17 by means of brackets sa 21 and connected at one end toy a conveyor trough 22, through which empty cartons are fed to the machine, and at its other end to a conveyor trough 23,' through which the .filled cartons are removed from the machine. The 35 cartons are carried lthrougggh conveyor sections 21 and conveyor troughs 22 and 23 :on an endless belt which rides on the bottom of these members and is actuated inthe manner customary in belt conveyors.

The cartons, which are represented as a known type consisting of a cardboard outer part 26 olded to form a cover 27 and which are lined with -waxed paper 28. In Figures 3 and 4, the cartons are shown in full with the exception of one in Figure 4 which is shown in section and as it would appear at the moment of receiving its charge of crackers.

' As the function of the machine .consists of Several distinct operations, which must be timed with onev anoher, each will be described separately.

The belt 24 runs continuously and tends to move the cartons through the machine in a regular flow but this flow is interrupted and made intermittent byV a locating mechanism which will now be described. Referring more particularly to Figures 1, 2 and 6, a bracket 29 is mounted on the side of conve or section 21 and has an arm 30 rocka ly mounted in its outer end. Spacers 31 and 31a are pivotally mounted in each end of arm 30 and extend throu h suitable slots in the side of section 21. has one end dpivoted to one end of arm 30 and Aits other en ivoted to the forward end of a lever 33 whic in turn is pivoted at 34 in a bracket bearing 35 mounted on post 15. A lever 36 is pivoted approximately midway of its length to a bearing 37 mounted on ost l5 and h`as a bifureated lower end w ich straddles a screw 38 inserted in the end of lever 33. A pin 39 is slidably mounted in a hole in ost 15 in such a tion that one end will a ut the upper en of lever 36 and its other end abut aA cam face 40 secured to the back of amutilated gear 41 fixed on the main drive shaft 42.

As gear 41 rotates, cam face 40 will make contact with pin 39 at certain intervals, as shown in Figures 2 and 5, andmove the upper end o ever 36 away from post 15 to which-it is pivoted, thus moving its lower end in the opposite direction. As the lower end of lever 36 is attached to the end of lever 33, this movement will be imparted to link 32 and arm 30 and cause spacer 31 tov y partially enter the interior of member 21, as plainly shown in Figure 6, thus stopping the movement of empty cartons through the conveyor but permitting the illed carton to travel away from the machine.l

l have shown the empty cartons being. dehvered through the rear of the machine and the filled cartons from the front of the machine but it will be understood that this dlrection may be readily reversedl by reversmg the movement of belt 24 and the timing of lever 36. y

'I he retarding of the empt cartons is plainly shown in Figure 3, it being understood that the conveyor belt 24 continues to move and the bottom of the cartons ,slide upon its surface in the manner customary in such conveyors. After gear 41 has made a pair of linksv 32` end of lever 36 will be drawn toward post 15 by the action of a spring 43 suitably connected between the lever and the post, thus reversing the movement of lever 33, link 32 and arm 30 which ca uses spacer 31 to be withdrawn from theinterior of the memvber 21 and the spacer 31* to. enter it. As

belt 24 is movin continuously, an empty carton is carried orwardly from its position yback of spacer 31 until it abuts spacer 31,

at which time it is in position for filling as shown in Figure 4, in which the carton is shownin cross section with its contents in place. It is understood, of course, that the movement of the spacers, and consequently the movement of the cartons, is co-ordinated with the other movements of the machine.

A trough-shaped conveyor end 44 is secured to. front posts 16 and has a roller 45 suitably mounted therein over which an endless belt 46 travels. A conveyor trough, leading to the source of supxply, is connected to conveyor end-44 and t e belt 46 moves therethrough; its upper half being supported by the bottom of the conveyor trough. As this conveyor is of the t e normally employed in moving material from placeto place, it forms no part of m invention and will not be further describe The material to be packed is placed edgewise on the conveyor belt, either by hand or mechanicall and is thus conveyed to the machine. n order to maintain the cakes or biscuits on edge, the conveyor trough must be first filled by hand with the'front end of the row of biscuits or cakes held uprightby the machine, as shown in Fi 3 and 4, and the material in the rear of the row held upright by the stacking machine or by elevating the rear end of the conveyor.

y At the beginning of the operation, the cake or biscuit in the front of the row of material `1n the conveyor is supported in an upright position by a lunger, ead 47 l(see Figure 3) v hichis a ed to a measuring plunger 48, the rear end of which is mounted in a guide bearing49 on a su port 50 attached to the rear posts 15. e forward portion of plunger 48 is supported and guided byan aperture in a plate 5]. which also forms the rear end of the measurin compartment.

-Movement is imparted ommaiu shaft 42 to plunger 48 through a gear 52 which meshes with mutilated gear 41 and is secured to a shaft 53 mounted in suitable bearings on the rear posts. An eccentric 54 is secured on shaft 53 and is provided with an eccentricrod 55 threaded into the eccentric strap 56 and held in adjustetfpositions by a jam nut. A lever 57 is ivo to a brace 58 on the rear posts an has its up r -end pivotally' connected to the outer en of eccentric ro'd 55 and its lower end connected to a link 59;

nosas-ta it and move plunger head47 from the posi- `the machine.

tion shown in Figure 3 to the position shown in Figure 4. As belt 46 is moving continuously, it is evident that the material will follow plunger head 47 to its rearxnost position, thus filling the measuring compartment of A shaft 61 is mounted in suitable bearings on rear posts and is rotated by ,meansA of a gear 62 which is on one of its ends and meshes with mutilated gear 41. A cam 63 is mounted near the center of shaft 61 and a disk 64, having a crank pin 65 settherein is'mounted on its other end. A rock shaft 66 is ,suitably mounted on rear posts 15 and has a grooved crank 67 engaging crank pin 65. A lever 68, bifurcated to clear cam 63,

is rigidly mounted near the center of rock shaft 66 and has its front end binrcatedj vertically, to straddle a support'rod 69 and a iilli'ng,plunger' 70, and bifurcated horizontally to straddle a pin 71 which extends through ,the f lling plunger. A filling plunger head4 72 is'suitably secured. to the bottom end of filling plunger 7() and is adapted to make contact with the tops of the material in the measuring compartment and force it into the waiting carton, as will be laterl described. The lower end of support rod 69 isjprovided with a pair of straps which connect to'each side plate o a measuring unit 73. i

Rockably mounted on center to iece 20 is a lever 74, the rear end of whc is bifurcated to accomodate a roller, 75 adapted to Contact with the cam 63. vThefront end of guides 78 and 7 8% through which rod 69 and filling plunger 70 slide.

As shaft v61 rotates, vcam 63 will engage roller 75, actuate' lever 74 and rod 69 and thus force measuring compartment 73 ownwardly. Simultaneously with the .rotationl of cam 63, disk 64 will rotate and actuatev rock shaft 66 through the engagement of crank pin and crank 67, thus moving the -feeding conveyor is prevented by outer end of lever'68 downwardly which forces the filling plunger to its lowermost position.

' -As plunger forward movement of the material in the standing .portlon 79 onthe pl r head.

As the movement of the outer en of lever head 72 moves downiivardly',

68 is much'greater than the movementof the outer end of lever 74, plunger head 72 will move much farther than will,the measuring unit. In other words, measuring unit 73 and plunger head 72 will move downwardly to a point adjacent the top of the 'carton to be lled, where the unit will remain stationary while the filling head 72 moves downwardly through the measuring compartment of the unit to a point approximately level with the top of the carton.A

The upstandingportion 79 of the plunger head is provided with a shouldered slot 80 (Fig.f8) in `which a slide 81 is slidably Amounted by means of a slide guard 82 rigidl secured to the rear side of its upper end. trigger 83 is pivotally connected to the rear side of slide guard 82 and is yieldingly held in its upper position by means of a tension spring 84 connected to its upper end and to guide 78a. yTrigger 83 isprovided on its rear edge with a pair of notches forming shoulders 85v and 85a which are adapted to en age a shoulder 86 formed on guide 78. en plunger head 72 is in its uppermost position e' shoulder 85n will contact with shoulder 86, as shown in Figure 3, thus bringing the lower end of slide 81 approximately even with the lower end of the upstanding portion 79 ofthe plunger head. As the plunger head moves downwardly, slide 81 will lcome in contact with the vtop of the slot 80 and be carried downwardly with it, against' the action of spring 84, until its lowermost position is reached when shoulder 85 on trigger 83 will come in contact with shoulder 86` and hold the trigger in this position until the lplunger head reaches its u permost position', as shown in Figures i 4 an 8. It is evident that slide 81 replaces upstandingportion 79 in holding the material in the conveyor against forwardmovemen(t,'initial plunger 47 having moved forwar A trip plunger 87, having a roller 88 mounted in its bifureated vforward end, is slidably mounted through guide 78 and held in its rearmost position by a compression spring 89 encircling thev trip plunger `with its ends abutting the guide 78 land a collar 90 fixed to the trip plunger. The rear end of the trip plunger Vis adjustably threaded` into a head 91 which is provided with a slot 92 adapted to engage api-n -93 secured to the lever 57 Due to the slot 92 and to the shorter leverage on lever 57, it is yevident that the forward movement of the trip plunger 87 will start at alater time and be at a much slower rate 'than that of the plunger-48, but adjustment is so made that the instant the plungerhead arrives lat its 4 forward position, the roller 88 on the tripplungerwill make contact with an extension 94 on vtrigger 83 and force same'out-I wardly so as to allow spring 84 to returnthe plunger ead 47 and completing a cycleA the trigger 83 to its uppermost position, thus bringin the materia in contact with of operation;

plate 51 and in the ends o the side walls of end slidabl secured to side piece tact with stop 106, thus :onve orend 44. Apaper guide 97 is hinged to si e plate 95 and is actuated by means of a bent rod 98, one end of which is secured to the hinged part of guide 97 and its other mounted in a cam slot 99 in plate 51. he guide 97 normally extends inwardly and downwardly from side-plate 95 so that, as the measuring unit is lowered, the lower edge of this guide may be inserted inside the carton and, as the unit approaches the lowermost point of its movement, rod 98 causes guide 97 to swing outwardly and engage one side of the Wai: paper` lining, thus clearing this side of the carton-1n preparation for receiving its charge of material.

A bottom iece 100 is hin d tothe side plate 95v an normally lies in a horizontal position to form a continuation of the bottom of the delivery conveyor and remains in this position until the measuring unit has nearly reached the lowermost point of travel when it swin downwardly and outwardly and allows tige material contained in the measuring unit to be deposited into the carton below. In its outward movement the bottom piece 100 engages the paper lining on its side of the cai-ton and forces same outward-ly to clear this side of the carton. A pinion 101 is rigidly secured to a rod around which portions of side plates195 and bottom piece 100v are bent to form a hinge; the rod being loosely held in the bent portions of plate 95 and rigidly held by the' portionsof bottom piece ,100'. Pinion 101 engages a rack 102, formed on a piece 103 which is provided with a slot '104. A

shouldered piece 105 is mounted in and over-v laps the sides of slot 104 and is rigidl A stop 106 is a justably mounted `on the edge of end plate 51, by means of a clam ing plate 107, and

is adapted to engage a s ouldered extension 108 on the upper end of piece 103 to prevent further downward movement. A coiled spring 109 has one end secured to shouldered extension 108 and its lower end secured to side plate 95", thus tending to hold extension 108 against the top of shouldered piece 105. As the measurin unit moves downwardly,lextension'108 will make congiece from f urther downwar movement and olding rack 102 stationary. As the unit tion member 111 is -means of suitable bo ireventing this provided with a downwardly extending 10 flange 110 on the inner side of whicha friclyeildably mounted by ts or screws encircled bg coiled ,springs 112, the ends of which a u t the adjacent faces of flange 110 and friction member 111 respective y, holding the latter approximately flush with the inner end of conveyor section 44. Hinge parts 113 and 113* are rigidly secured to the front end of plates 95 and 95 res A front paper guide 114 is mounte between hinge parts 113 and 113 by'ineans of a short pin assing throuvh hinge part 113 and by a gent rod 115 aving one end extending through hinge part 113 and its other end engaged in a cam slot 116 formed in a plate secured to the inner end of conve or section 44.- Front guide 114 is provi ed with a slot slight] larven than friction member 111 over w ich the front guide is adapted to swinig. In its normalposition the front guide iangs nearly vertically an in the same plane with the friction member 111. As the measuring yunit approaches the end of its downward movement, 4bent. rod 115 will be actuated by cam slot 116 in such a manner as to cause frontl ide 114 to swing forwardly and engage t e paper lining at the front vnd of the carton. l

A division plate 117 is mounted between side plates 95 and 95.* near their-rear ends and is bifurcated on its center lineto provide a passage for measuring plunger 48. Lugs 118 extend forwardly from the lower corners of division plate 117 and have a rear paper guide 119 journaled between them in such a manner that the upper -front edge of theV ide lies-in approximately the same vertica plane as the ace of plunger head 47 when same is inl its rearmost position. A

bifurcated extension 120 is formed on the top of rear guide plate 119 and extends rearwardly at approximately right angles to the body of the ide. A pair of coiled sprin 121 have their upper ends secured near t e upper edge'of rear plate 51 and yieldingly support a stop 122 w ich is reduced alo its central rtion so. that it may be strad ed by thefbifurcated extension 120`on rear guide 119 which is adapted to slide freely on either side of the 'reduced' rtion and to make positive contact with t ebottom portion of the'sto A retaining strip 123, of the saine widt as the reduced portion of stop 122 -is superimposed on the stop and held in 'tion by counter-sunk head screws which extend through a vertical slot` 124 and are threaded into rear plate 51.

ower end of stop-122 maintes will be engaged by extension 120 and yieldingly hold same against further downward movement which will cause rear guide plate 119 to swing rearwardly and engage the paper lining to clear this end of the carton for the placing of thc material therein. As unit 73 is ada ted to move slightly farther, stop 122 will 1c carried with it due to the yielding of springs 121.

The different movements of the machine are timed by means of cam 63, eccentric 54, disk 64 and cam face 40, the movements of 'which are intermittent due to the fact that gear 41 is a mutilated gear which alternately meshes with .gears 52 and 62. The inp' rigidly secured to gear 41y and has one semicircularportion, the radius of which is equal to the pitch radius of gear 41, and a smaller semi-circular portion, which is of such size as to clear the edges of plates 126 and 127. Plates 126 and 127 are rigidly secured to gears 52 and 62 respectively and are circular in shape with the exception of a cut-out portion in each which has a curved edge conforming to, and adapted to contact with, the periphery of the larger semi-cir, cular portion of plate 125. These gears and plates are 'plainly shown in Figures .1 and 5 and, as this movement is well known, it will not be further described.

The machine operates as follows: Measuring plunger 48 is placed in its rearmost position with slide'81 held in its lower position by trigger 83, as shown in Figure 4, and the member 60 .loosened so thatthe measuring plunger may be moved forwardly until the distance between the vface of the measuring plungerv head 47 andthe rear face of slide 81 is slightly greater 'than the total length of the stack of cakes or crackers which it is desired'to. place in each carton. Member 60 is then rigidly re-secured to the measuring'plunger. The material to be packed in the cartons is properly stacked in the material conveyor and a supply of paper lined cartons placed in the carton conveyor;

it being assume-d that the supplies of ma terial and cartons will be maintained.

Power is then applied which will cause the movement of belts 24 and 46 in the proper directionsland the rotation of main shaft 42 in a clockwise direction. This will cause gear 4l to mesh with gear 52 and rotate shaft 53, and consequently eccentric 54,

in an anti-clockwise direction and move ec' Acentric rod 55 rearwardly. This movement will cause measuring plunger 48 and. tri

`moves the upper end of lever 36 outwardly,

which causes spacer' 31'to enter the interior of 'conveyor section 21, as previously ex plained, retard the forward movement of the cartons and allow the carton directly under the measuring unit. to be carried away.

ContinuedV rotation of main shaft 42 causes continued rotation of the eccentric 54 and the return of-plunger 48 to its original position, at which time pin 39 will leave cam ace 40'and the positions of spacers 31 and 31a will be reversed due to lthe, action of spring 43, as previously explained; that is, spacer 31 will be withdrawn from vthe interior of section 21 and spacer 31a extended into it so that an'empty carton may be positioned directly under the filling mechanism. At this point, gear 41 will disengage gear 52 and en age gear62 attached to shaft 61, which wil be rotated in an anti-clockwise direction, together with the cam 63 and disk 64 mounted thereon. Cam 63 and lever 74 will be in the positions shown in Figure 3 while .eccentric 54 and lever 57 will be in the positions shown in Figure 4. Rotation of shaft 61 will cause the faces of cam 63 to elevate roller 75,. mounted in lever 74, and force rod 69 and measurin unit 73 downwardly, as previously explained. A t the same time, crank pin 65 on disk 64 will actuate groovedcrank 67, .rock shaft 66, and

lever 68, thus forcing filling plunger 70 downwardly.

As the measuring unit and filling plunger move downwardly, the unit 7 3 will approach sufficiently near the cartonV for the paper guides to engage the edgesof the lining and clear the opening in the carton, atwhich time bottom 100 flies open and downward movement ceases, due to roller 7 5 havingreached the highest point of the cam' 63. Shaft 61 continues to rotate until crank pin 65 has moved a sulicient distance to cause lling plunger head 72 to travel toa point adjacent the lower edges of the paper guides and of bottom piece 100. shaft 61 reverses the movement just described and returns the parts to their starting positions.
